Sorry if this is a dumb question, but how can a sensor with 12bit ADC have more than 12ev of dynamic range in screen view? It seems like quantization noise alone should limit the dynamic range to 12ev. I can see how print view would add a half stop of range since in this case you averaging about 2 pixels to make one, so noise is sqrt2/2 of what is was before normalization. Anyway, if someone could explain how this 12bit sensor can have more than 12ev in screen view, it would be appreciated!
